python在使用时，可能会使用ssl模块。所以在编译时，可以直接将ssl模块编译进去。

yum install opensslyum install openssl-devel -ycd Python-3.6.6vi Modules/Setup #修改文件如下 # Socket module helper for socket(2) _socket socketmodule.c # Socket module helper for SSL support; you must comment out the other # socket line above, and possibly edit the SSL variable: SSL=/usr/local/ssl _ssl _ssl.c \ -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \ -L$(SSL)/lib -lssl -lcrypto然后进行编译安装即可
